-ments in Drawing Guides, of which the following lis a specification.

The present invention relates to a drawing guide, and has for an object to provide a templet `orguide platefpeculiarly constructed to facilitate the laying olf-,of blocks, squares, streets, alleys, and-.other lines of division and locations ofiobjects-on plats for use by tele' phone 'construction engineers, or for other engineering andlikework where rough plats or lay-outs are inade Aon different locations.

.At the present .time in making drawings of. azplant lto he re1noved,1erected or changed, it is :necessary l:for the :engineer yto `prepare a rouglnorcrudedrawing and turn it over to a-draftsman for redrawingor copying it at least roughly to a scale sufficient to show the general featuresofithe plant. ,By the use or the 1presentinvention the :engineer may use theaguide eimma-hing` out his rough drawings and the drawings will be roi sufficient accuracy to eliminate the step of having the @plat 5redrawn .by fthe vdraftsman. This saves considerable time and enables the engineerto carryout ,his individual designs and at the same. timeA ensures more accurate lay-outs.

The invention further ,aims at the kprotions of'theiinstruinent-to insurethe proper :spacing fof the various ylilies Vand devices, to indicate streets, alleys,-andother obgects in their correct proportions.

The above and vvarious other objects and advantagesof this invention will be in part describedand Sin part understood from the following detail )description `of the present preferred embodiment, the-saine being illu sti-ated :in the accompanying drawings,

meets the long straight edge `11.

Referring to the drawing, the guide or drawing instrument comprises a body plate 10 which may he constructed of celluloid or other suitable material, and the body sheet 1() may be transparent if so desired. The body sheet 10 is preferably thin so as to accommodate the point of a pencil without K pencil, and is also provided witha base edge y 12 at one end which is also straight and'at right angles .to the edge 11. yThe opposite longitudinal edge of the plate 1() is formed with a straight edge 18 extending but little more than halrthe length of ,the plate 10 and which is in ,parallelism with the klong straight yedge 11. The edge .13 terminates intermediate the plate 10 in ,a shoulder let which is provided witharecess or notch 15 of substantial width whichterminates at the base vof a curved'edge 16 which is rounded oir `to the opposite end of the plate v10 and The shouldered side of the plate 10 is .provided ywith an elongated sloty 17 lying closelyad- ,jacent to and parallel with the straight edge Y13 of the plate, and which is adapted to coopcrate with straight slots 18 and `19 formed interinediately in the lplate y1() in spaced ren ,lation` to each other and to the slot 17. yAll of the slots 17, 1S and719 are in parallel relation to each other, and the body vplate 10 ,is provided with small perrorations 20and 21 therethrough to receive the point of a pencil, the perforations 2O rands21 being .spaced in a longitudinal direction ronithe the plate 10. -rlhe-bodyxplate llisfurther provided, -near the straightedge y11, with a shorter slot 22 and a pair of spaced but longitudinally aligned short vslots 23 and 24.

The slot 22 isxspaced `from theslots 23 and Qltoward the edge 11 ofthe plate,.and the plate 10 is provided with a short slot25 in longitudinal alignment with slot `22 but spaced therefrom a distance equal substantially to the space-between the adjacent ends ofthe slots 23 and 24. The plate 10 is also provided near its reduced end vwith a single perforation 26 for cooperation with t-he vslots A23 and 24, and near its base andwith yanother vsingle perforation 27 adapted to receive a pencil point for determining certain angular relations with respect to the slots 17, 18 and 19, and the perforations 20, 21 and 26.

At the reduced end of the plate 10 there is provided slot 28 of the configuration ot a direction indicating arrow, and spaced outwardly from the point of the arrow configuration 28 is a perforation or slot 29 of suitable configuration for indicating a definite direction, such as N moaning north. The body of the plate 10 is also provided with a number ot slots or perforations 30, 31, 32 and 33 which are given difierent configurations for indicating different devices illustrated upon the drawing. These indicating configurations or symbols are preferably arranged in a row between the slots 17 and 18 so as to be in a position for easy access.

1n using the improved drawing guide, reference may first be had to Figs. 1 and 3 wherein to draw a street block with a T alley, the guide plate 10 is placed upon the drawing sheet in a horizontal position and a pen` cil point is inserted in the slots 18 and 19 and in the slots 23 and 24 to form respectively the lines 34, 35, 35 and 37 on the drawing sheet. Next swing the guide plate 10 around into a vertical position so that the slots 22 and 25, 19, 18 and 17 are so positioned with respect to the lines already formed as to guide the pencil in forming the lines 38, 39, 40, 41 and 42 respectively. To draw the remaining lines 43, 44 and 45 of the blocks, any of the straight edges 11, 12 or 13 may be utilized, although, of course, any of the slots in the body plate may also serve the same purpose provided that they be of suitable length. This procedure may be repeated any number of times to make the desired drawing, although Fig. 3 shows the block with the T alley duplicated but once.

Fig. 2 shows another type of drawing illustrating the various portionsof a plat re- -quiring revision and change. In order to make this drawing, the various blocks 46 are laid out with the aid of the slots 17, 18 and 19, and when this is done to the desired number as shown in Fig 2, the guide plate 10 may be placed upon the drawing with the slot 17 over the line 47 of one of the blocks and a pencil point inserted in the aperture 27, marking the drawing sheet and again marking the sheet by inserting the pencil point in the recess 15 at the base ot the curved edge 16. These two Points give the straight line 48 which is spaced from the lines 49 of adjacent block-s and which are correctly proportioned as to spacing in order to accommodate the various devices used by the engineers. The plate 10 is now manipulated to bring the various slots or perforations 30, 31, 32 and 33 over the space between the lines 48 and 49 as shown in Fig. 2 for setting forth onthe drawing paper symbols according to the configurations of the perforations. The line 50 passing between the ends ot the blocks to designate a cable line or the like, and the configuration 51 which is formed by utilizing the perforations 30 may be produced by proper shifting of the plate 10 over the drawing sheet.

In laying out the plat shown in Fig. 2, line 50 indicates a terra cotta tile duct with one or more cable openings therethrough lwhich lead from an exchange office, in telephone installation or the like, to a manhole indicated at 51. From the manhole 51 the cable is pulled through a pipe 52 which leads to a pole 53, the pipe 52 being under ground and the cable being carried upwardly to a suitable height of about eight feet to a terminal box 54, and from this box the cable is Carried outwardly and hung upon the poles 53 by means of the various devices used in this class of work. 55 designates small terminal boxes to which small groups of wires from the cable are led and from which the drop wires extend which lead to the individual houses or buildings for connection with the call boxes or telephone instruments. rlthe anchors for bracing the poles 53 are indicated at 56 in the plat and show the proper positions of the same to keep the poles in line and `from pulling in either one direction or the other.

It will loe noted that there is a predetermined and definite relation between the various slots and perforations not only as to length, but as to size and location in the body plate 10.

It will be noted that the perfor-ations 20 and 21 are so spaced from the upper ends of the slots 18, and 19 that lines of various degrees of inclination may be readily determined by marking with a pencil point through the perforations and through the adjacent ends of the slots. The other perforations 26 and 27 are likewise positioned definitely with respect to the slots and the symbol' perforations in line therewith and with the base of the curved edge 16.

It is, or" course, understood that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, and being limited only by the scope of the following claims.

`What is claimed is 1. A drawing guide comprising a plate having a. plurality of spaced apart parallel slots therein, said plate being of substantially rectangular form at one end and having a curved edge at its other end, there also being a plurality of symbolic perforations in the plate in definite relation to said slots and to an edge portion of the plate for locating the symbols with respect to blocks formed by said slot-s.

2. A drawing guide comprising a plate having a rectangular coniiguration at one end, said plate having a stepped portion spaced inwardly from the opposite end and terminating in a curved portion, there being in the platea plurality of spaced parallel slots, a plurality of symbolic perforations in deiinite relation to said slots for deterf mining the position of the symbols with respect to the lines drawn with said slots.

3. A drawing guide comprising a flat transparent plate of rectangular form at one end and provided With a shoulder at one side near its other end andrterminating in a curved edge leadingyfronr the base of Said shoulder', there being a plurality of laterally l and longitudinally spaced apart slots formed in said plate, said plate yhaving perforations spaced from the ends of certain of said Slots to determine various angular positions of street and alley lines with respect to the sides i of the blocks indicated by the longitudinal slots, there also being a plurality of perforablocks.
